Exodus 19:3b-8

3Then Moses went up to God; the Lord called to him from the mountain, saying, Thus you shall say to the house of Jacob, and tell the Israelites:
4You have seen what I did to the Egyptians, and how I bore you on eagles wings and brought you to myself.
5Now therefore, if you obey my voice and keep my covenant, you shall be my treasured possession out of all the peoples. Indeed, the whole earth is mine,
6but you shall be for me a priestly kingdom and a holy nation. These are the words that you shall speak to the Israelites.
7So Moses came, summoned the elders of the people, and set before them all these words that the Lord had commanded him.
8The people all answered as one: Everything that the Lord has spoken we will do. Moses reported the words of the people to the Lord.
